“The greatest adventure is what lies ahead. Today and tomorrow are yet to be said. The chances, the changes are all yours to make. The mold of your life is in your hands to break.” J.R.R. Tolkien

No, not a direct quote by any means. "Good and ill have not changed since yesteryear; nor are they one thing among Elves and Dwarves and another among Men. It is a man's part to discern them, as much in the Golden Wood as in his own house." - Aragorn
